Tools Required to Fix Air Compressor Hose Leak
Before starting your air compressor leak fixing process, ensure you have the following tools at the ready.
- Air compressor hose repair kit (specifically a coupler and 2x hose clamps)
- Cutting knife or other appropriate sharp
- Flat head screwdriver
- Electrical tape
- Plastic bag
Step by Step Guide to Fix A Leaky Air Compressor Hose
We can break down the whole process into the following 5 simple steps:
- Locate the leak
- Cut the hose
- Place coupler fitting inside hose
- Tighten hose clamps
- Wrap plastic bag around
Now lets take a look at these steps in greater detail.
Locate the Leak
First of all, locate the exact position at which your air compressor hose is leaking. If your hose is leaking at the joint then you may be better of buying a full replacement. If your leak is along the length of your hose then follow the rest of these steps.
Cut the Hose
Once you have located the leak on the hose, now you can cut the hose either side of the leak. Use something sharp like a suitable knife or specific tool for cutting wires/hoses and ensure that you make a clean cut so it is easy to complete the following tasks.
If the hose is too thick then seek professional help.
Place Coupler Fitting Inside Hose
First of all take your two hose clamps and put one over each cut end of the hoses. Then take your coupler fitting and fit it into each part of the cut hose.
If you’re struggling to get the coupler in the tube, use a lighter or match to heat up approximately 1/2″ from the end of the hose to allow it to expand more easily.
Tighten Hose Clamps
Now tighten them around the coupler to hold the hose and fitting together. However, don’t tighten them too much as this can cause them to break.
Wrap plastic bag around
An additional step, to stop the hose fixing getting stuck against chips in the floor or being pulled up a ladder, is wrapping a plastic bag around the centre of the connection and then using electrical tape to hold it in place.
Ensure that you make a slope similar to that described in the youtube video to follow.
After completing these steps, you can reconnect your hose to your air compressor and start the system. Check the repair and ensure it is not leaking any more!
Note: You should buy the best available air compressor hose repair kit regardless of the costs, you need the highest quality to ensure the repair works. If you have multiple leaks along the hose length then it is recommended that you replace your hose with a new one.
